We're dividing 517133 by 1 
The aim is to understand the frequency of 1 in 517133.

On to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Step 2:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 1 from 1, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Going ahead to step 3:
7 divided by 1 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 517.0
If we subtract 7 from 7, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Advancing to step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 5171.0
Subtract 1 from 1 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Step 5:
1 goes into 3 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 51713.0
Deduct 3 from 3 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Step 6:
1 goes into 3 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 517133.0
Subtract 3 from 3 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 517133.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 517133.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 517133.0 and a remainder of 0.0.
